The accident was reportedly caused by two tractor trailers that came up upon slow-moving traffic. Police say one of the trailers may have hit the limo bus in the rear, causing it to overturn. In total, six vehicles were involved, three people -- including the former Saturday Night Live star -- were critically hurt, and one person is in fair condition.

Morgan was rushed to Robert Wood Medical Center, where he is being treated.

The actor was a cast member on SNL from 1996 until 2003. He has four children, including a baby girl who is turning 1 next month. This is a developing story and we don't have more details on his condition after what sounds like a horrifying accident, but we'll keep you posted.
